Building materials are the material foundation, buildings and structures is along with the social production and the development of material science and development, the development of human society with material of the invention and development. Road and bridge construction is an important part of civil engineering, road construction material was used in subgrade pavement, Bridges, tunnels and other various parts of the various components and structures and eventually constitutes the structure of the material.

As large-scale expansion of China's highway construction, road building materials of use and development is becoming more and more fast, the traditional building materials are widely used in foundation engineering, but has become increasingly cannot meet the rapid development of highway construction of high standard engineering requirements.

In modern road construction, cement concrete, steel, reinforced concrete and asphalt and asphalt concrete is an irreplaceable material structure, and a new type of alloy materials, organic materials, new geotechnical materials, chemical building materials and various kinds of composite materials and so on also occupies an important position.

Building materials of solid materials after crushing, internal change of crystal structure, surface energy increases, the surface area of the unit mass increases, can improve the physical and chemical reaction speed, easy to mix, improve the effect of homogenization, and create favorable conditions for drying, storage and transportation.

Impact crusher is applied to industrial production in 1924. Impact crusher is a kind of the use of impact energy to crushing material crushing machinery. Very suitable for construction waste broken, when the machine work, under the drive of the motor, the rotor high-speed rotation, the material into the plate hammer function area, and the rotor plate hammer impact broken, and then again to counter device is broken, and then back to the board from the back plate hammer function area is broken again, this process is repeated, material from big to small into one, two, three, back cavity repeated broken, until the material being broken to the required size, is being exhausted from port discharge. Adjust the clearance between the back frame and rotor can achieve the purpose of the material discharging granularity and material to change shape.

Impact crusher and hammer broken, as are the impact kinetic energy to crush materials crushing machine, the working principle and structure of performance, there are many similar places.

Impact crusher hammer head and the rotor is rigid connection, fracture zone within the chassis back blow type crushing Angle. After the big materials from inlet feeding, first by high speed rotating hammer bottom-up impact crushing, and are quick to impact plate hammer broken, or bounce back broken zone, again by hammer impact, continue to repeat the process. In the back and forth on the way, the material will collide with each other, between produced from crushing. After many, many functions of composite grinding, if material particle size is smaller than the gaps between the back plate and blue, from lower chassis discharging mouth education If it is greater than the gap will be rigid hammer head milling and grinding broken, until discharge.

Thus, impact crusher in the crushing effect is mainly the following three aspects:

(1) Free crushing

(2) Rebound broken

(3) The milling and broken

It can fundamentally solid material crushing requirements needed to complete the construction materials.
